Autumn
During the autumn the leaves turn yellow and brown. With all the wet and windy weather leaves fall to the ground. In a few days trees will be bare. When there’s less sunlight, deciduous trees do not produce chlorophyll, which they use to convert light into energy to grow. Chlorophyll is the pigment that gives leaves their green colour. The tree without the leaves needs less water and energy to stay alive during the Winter. The fallen leaves add nutrients to the soil.
